Thanks for the advice. I was actually leaning towards the HPSP route for those exact reasons, but having kids early is really important to us (especially her) and USUHS seems like the best way for me to pursue a career in medicine and for us to have a family before we're in our 30s. I've by no means made a decision, I'm just as open to moving back home and living near family to help out, or to a med school in a area with super low cost of living (are there any that are half decent?) and live off the $2000 stipend, but right now we are leaning towards USUHS. Still a lot of research to do.
I am the wife so maybe I can offer a little bit of a different perspective to this situation.
We did the HPSP route, had 3 children during medical school and I was able to be a stay at home mom. I do not feel like we lived any better than our non HPSP counterparts (save the "mental anguish" that we saved by being "debt free")
We and our friends, lived in a government subsidized housing unit paying next to nothing for rent (something like $200/month). Friends took out maximum loans each year (about 50,000/year....30k going towards tuition, the other 20k to live off of), in addition all the medical student families were able to qualify for medicaid, food stamps and wic. Some had to swallow pride and apply, but if you want to have kids, family and stay at home wife I don't think that HPSP or any military scholarship is your only option.
Those same friends are now graduating residency and looking for "real" jobs. My husband is applying to residency. Although we have made more money than our civilian counterparts these past few years, we haven't been able to really enjoy it b/c we have always known that we will be going back to residency so all the extra money is waiting for us in the bank so that I can continue to be a stay at home mom to 4 children w/out suffering quality of life. Savings in addition to GI Bill should help sustain us through the "drought". My opinion is that it will be a lot harder going back to the lesser income than it would have been straight out of medical school when you were already used to living on next to nothing.
So yes, HPSP and the military do offer you "financial perks", but I don't think that we lived any more lavishly than those in our exact same situation (married w/children, stay at home mothers). So once again please don't do it for the money.
My perspective on military life thus far is positive. We chose to live on base and while there are many oddities about it we love it. The convenience, the schools, the "olden days" feel to the neighborhoods, cheap entertainment, etc. I am particularly fond of the fact that life is good for my kids...they can play outside and run around the neighborhood w/out me worrying about them too much. The roads are quiet, especially not living on a main route through housing or to the school. Bad side to this: we live on a small base, everyone knows your business for better or worse!
We have been able to fly on military aircraft to visit family and vacation (we are OCONUS) for free. My husband has not deployed, but has been on numerous TDY's. Be prepared for a whole lot of headache as you go from being a civilian intern to being an O3 stationed at a base for the first time. Took a long time for us to start getting paid and nobody understands how it can be your first base and why you have no paperwork to ease the transition and "everything should have been done by your previous base."
Biggest negative: my kids are now 4 years older. I would have much preferred it when they were babies and weren't able to verbalize how much they missed dad and how much it sucks that he is gone all the time, especially since they are so used to him being around now b/c he works in the clinic. Also we weren't really involved in anything outside the home like we are now so he also will miss much more of their lives by not being able to go to their athletic games, recital performances, school functions, etc. that he wouldn't have missed had he gone to residency 4 years ago (b/c they would have been too little to participate in these things).
So although we aren't far into military life I wanted to offer our story. We have enjoyed each step, but being in the military has made some things a little more difficult. Having said that, we have definitely had experiences that we never would have been able to come close to experiencing had we not been in the military.
